Nick Mathewson 65d1f83d2c Extend [unused_io_amount] to cover AsyncRead and AsyncWrite.
Clippy helpfully warns about code like this, telling you that you
probably meant "write_all":

    fn say_hi<W:Write>(w: &mut W) {
       w.write(b"hello").unwrap();
    }

This patch attempts to extend the lint so it also covers this
case:

    async fn say_hi<W:AsyncWrite>(w: &mut W) {
       w.write(b"hello").await.unwrap();
    }

(I've run into this second case several times in my own programming,
and so have my coworkers, so unless we're especially accident-prone
in this area, it's probably worth addressing?)

This patch covers the Async{Read,Write}Ext traits in futures-rs,
and in tokio, since both are quite widely used.

changelog: [`unused_io_amount`] now supports AsyncReadExt and AsyncWriteExt.
